Wedge device.
Background technology
, it is necessary to be simulated to the wind profile of different landforms in wind tunnel test is built, the method generally used now
It is passive simulation method.The way of usual passive simulation method is that building wind turbine apparatus incoming is caused not by different blocking devices
Same obstruction, make wind speed that required distribution be presented in vertical direction（That is wind profile, also known as wind cut open）.Blocking device mainly includes
Wedge and roughness element.Wedge stands on upwind, and upper and lower width is different, causes different obstructions to make upper and lower wind speed not to air
Together.
In general way is substantially to determine the size of wedge by empirical equation and numerical simulation before the test at present, so
Post-processing makes wedge, is then tested in actual wind-tunnel.Following problem be present in this way：
1st, width is difficult to change after wedge completes.Because of the complexity of wind tunnel test situation, using analogy method system
The wedge of work is difficult the requirement for accurately meeting experimenter.Tested according to this wedge, test data will necessarily be reduced
Precision, cause the inaccuracy of result of the test.If remaking wedge, just necessarily cause experimentation cost increase and the test period
Increase.
2nd, the wedge to complete can only meet the wind speed profile modeling under single scaling factor, if carrying out more scaling factor works
The experiment of condition causes increasing for experimentation cost it is necessary to separately make wedge.
The content of the invention
